Using static redis connections in multithreaded env in Java

I want to improve the performance of my Redis read/writes, by reusing the connection object. So, I am making it static in the class, and my get() and set() functions are using this static connection.

In a multithreaded environment, can this cause data corruption? As in, since the connection is static, can 2 threads access it at the same time and data meant for one, be sent to the other?

I am using Lettuce lib in Java.

class RedisServiceLocator {  static StatefulRedisConnection<String, String> redisConn = null;  // constructor  public RedisServiceLocator() {    // create client and get connection if null    if(RedisServiceLocator.redisConn == null) {      RedisClient redisClient = RedisClient.create(redisURL);      RedisServiceLocator.redisConn = redisClient.connect()    }  }  // set  public void set(String key, String val){    RedisServiceLocator.redisConn.sync().set(key, val);  }  // get  public String get(String key){    redisConn.sync().get(key);  }}
